TECHNICAL FIELD

The present invention relates generally to personal protective equipment, and more particularly to a face shield device having an integrated safety lens.

BACKGROUND

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

The COVID-19 pandemic of 2020 has ushered in a new era of everyday use of personal protective equipment (PPE), such as facemasks and face shields, for example. To this end, many local governments mandate that users wear some type of face covering at all times when leaving their home. Moreover, employers are increasingly requiring their employees to wear both a cloth facemask and a transparent face shield at all times while on company property.

Although this requirement helps to reduce the spread of contagions, there are increasing numbers of complaints by workers that such a requirement interferes with other requirements pertaining to different types of safety devices that must be worn while performing certain activities. One such instance is found in manufacturing, and fabrication-type jobs, which require users to wear OSHA compliant eyewear/safety glasses at all times. In this regard, many users note that when looking through both the safety glasses, and the face shield, their vision is impacted owing to the differences in materials. Moreover, wearing such glasses beneath the face shield is uncomfortable as the distal end of the glasses engages the inside surface of the face shield which leads the user to constantly adjust one or both of the devices.

Accordingly, it would be beneficial to provide a face shield having an integrated safety lens that is capable of providing satisfying both OSHA and COVID-type concerns, so as to overcome the drawbacks described above. Additionally, it would be beneficial to provide a neck enclosure which can function to protect the neck of a wearer from lightweight debris and/or mosquitoes when working outdoors.

SUMMARY OF THE INVENTION

The present invention is directed to a face shield device. One embodiment of the present invention can include a lightweight, flexible, and fluid impervious transparent shield body that is sized to cover an entirety of a human face. A headband can be secured along the top of the shield for securement to a user's head, and a foam member is positioned along the top inside portion of the face shield for securement onto a forehead of the user.

In one embodiment, a safety lens is positioned within an elongated horizontal opening along the face shield at a location beneath the foam member. The safety lens can be secured onto the face shield by a frame and can provide impact resistance onto the device. In the preferred embodiment, each of the face shield, the foam member and the safety lens can include a curved shape.

In one embodiment, a neck enclosure that is constructed from a breathable mesh material can be permanently or removably secured onto the outer edges of the face shield. The neck enclosure can include a drawstring and cord stop for allowing a user to adjust and selectively tighten the enclosure about their neck while wearing the face shield device.

In each of the drawings, identical reference numerals are used for like elements of the invention or elements of like function. For the sake of clarity, only those reference numerals are shown in the individual figures which are necessary for the description of the respective figure. For purposes of this description, the terms “upper,” “bottom,” “right,” “left,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention as oriented in FIG. 1.

As shown in FIG. 1, the device 10 can include a shield 11 having a headband 12, a forehead engaging surface 14 and an integrated safety lens 21.

In one embodiment, the shield 11 can be constructed from a single piece of transparent material having an outside facing surface 11 a, an inside facing surface 11 b, a top end 11 c, a bottom end 11 d and a pair of side edges 11 e and 11 f. In the preferred embodiment, the shield can include a one-size-fits all shape and size that is suitable for covering the face of an adult user.

The shield 11 can preferably be constructed from a thin (e.g., 1 mm to 3 mm) piece of flexible, transparent, and fluid impervious material such as polyethylene terephthalate plastic (PET), for example, so as to allow a user to easily see through any portion of the shield body 11. Of course, other embodiments are contemplated wherein the shield is constructed out of different materials, and/or includes an opaque or semi-opaque surface.

In one embodiment, a retention strap 12 can be connected to the shield and can function to secure the shield onto the head of a user. In one embodiment, the retention strap can include two elongated bands that are joined together by an adjustable clip 13 or other such device so as to be adjustable in nature. Of course, other embodiments are contemplated where the retention strap can be constructed from a single elastic band that can stretch to accommodate a user.

Although illustrated with regard to a horizontal orientation, other embodiments are contemplated wherein a plurality of elastic or adjustable straps are provided so as to engage the head of a user horizontally and vertically (e.g., over the crown of the wearers head) as are known in the art.

In one embodiment, the forehead engaging surface 14 can comprise a foam member that is secured to the inside surface 11 b of the shield along the top end 11 c. The foam member 14 can be made from any number of different pieces of generally soft, cushioned materials such as polyurethane foam, for example, and can function to provide a separation distance between the shield body 11 and the face of the user. The foam member 14 may be secured to the main body via any number of connectors such as glue or resin, for example, and can extend downward in a substantially vertical position without obstructing the vision of a user while looking forward.

In one embodiment, a plurality of openings 14 a may be provided along the foam member 14 in order to allow air to circulate. Such a feature beneficially reducing the tendency for the inside surface of the shield 11 b and the below described lens 21 to fog.

In the preferred embodiment, the shield 11, the foam member 14 and the below described safety lens 21 will include a curved orientation so as to protect the front and sides of a user's face from being exposed to spraying liquids, such as bodily fluids expelled by a sneeze from a nearby person, along with the eyes of the user.

In one embodiment, an elongated opening 15 can be positioned through the shield at a location beneath the foam member 14. In the illustrated embodiment, the opening includes a generally rectangular shape; however, any number of other shapes and sized openings may be provided.

As shown best at FIG. 2, a generally rectangular-shaped safety lens 21 can be positioned within, through or along the opening 15 of the shield 11. As described herein, the safety lens can be constructed from any number of thin (e.g., 1 mm to 3 mm) transparent and impact resistant materials such as Polycarbonate plastic, for example. In various embodiments, the lens may include optical features such as tinting, magnification viewing, or may be customized to a vision prescription of a user.

In either instance, the safety lens can include a shape and a size that is complementary to the shape and size of the opening 15 so as to be secured therein. In one embodiment, the safety lens 21 can be secured onto the shield body 11 by a frame 22 such as tape or clear plastic braces having resin or other such connectors thereon to prevent movement and/or separation of the lens 21 from the main body 11. In this regard, the safety lens can be removable in nature or can be permanently connected to the face shield 11.

Although described above as including particular shapes or materials, this is for illustrative purposes only. To this end, the safety lens can include any number of different shapes, sizes and materials, and can be placed at any desirable location along the shield body so as to be positioned adjacent to the eyes of the wearer. Likewise, the opening 15 can include any number of complementary shapes so as to receive the lens 21.

FIG. 3 illustrates one embodiment of the device 10 in operation with a user 1. As shown, when the device is secured onto the user's head by the strap 12, the shield will be separated from the users face by the foam member 14 and the safety lens 21 will be directly in front of the users eyes. While wearing the device 10, the entire users face will be shielded against fluid splatter owing to the curved surface of the shield, thus reducing risk of contracting a virus, and the user's eyes will be protected against impacts from foreign objects, thus remaining compliant with various safety regulations.

FIGS. 4 and 5 illustrate one embodiment of the device 10 that further includes a neck enclosure 40 that can provide a breathable enclosure along the sides and bottom of the facemask. In this regard, the enclosure 40 can function to protect the face of a user from contact with external flying objects such as debris encountered in a construction setting and/or insects such as mosquitoes when working outdoors. Additionally, the net-style enclosure can be used by workers in the food services industry to prevent facial hair, sweat and other contaminants from contaminating food that a user is handling.

As shown, the enclosure 40 can include a body section having an inside-facing surface 41 a, an outside-facing surface 41 b, a top end 41 c, a bottom end 41 d, and a pair of side edges 41 e and 41 f. The main body will preferably be constructed from a lightweight breathable mesh material such as cotton, polyethylene, polyester, polypropylene, or nylon netting, for example.

In various embodiments, the enclosure 40 can be permanently or removably secured to the shield body 11, via connectors 42 such as opposing strips of hook and loop material, or via adhesives such as glue or resin, for example. In the preferred embodiment, the top end 41 c will be secured onto the retention strap 12, a portion of the sides 41 e and 41 f of the net body can be secured along the entire length of sides 11 e and 11 f of the shield body 11, and the middle portion of the net body can be secured along the entire bottom end 11 d of the shield body, so as to allow the lower half of the shield body to extend below and beneath the face shield.

Additionally, the bottom end 41 d of the net body can include a channel 43 into which an elongated drawstring 44 can be positioned. The ends of the drawstring being connected to an adjustable cord stop 45 for allowing a user to selectively tighten the net during use. Alternatively, or in addition to the drawstring, the bottom end 41 d may also include a resilient band, for selectively closing the net around the neck of the wearer.

Although illustrated with regard to having both the safety lens 21 and enclosure 40, those of skill in the art will recognize that embodiments of the presently claimed invention are contemplated wherein only one of these features are provided.

Accordingly, the above-described face shield having an integrated safety lens provides a novel way to satisfy workplace and virus-type concerns, in a manner that is not rendered obvious by previously known face shield devices.
